UNITED STATES JOSEPH W. REFORD, OF NEW YORK, N. Y.,AASSIGNOR OF ONE-HALF HIS RIGHT TO WILLIAM WATT, JR., OF SAME PLAGE.

IMPROVEMENT IN THE PURIFICATION 0F FILTERING AND OXYGENATING SUBSTANCES WHILEWITHIN THE RECTlFYlNG-CYLINDER.

Specification forming part of Letters Patent No. 159,451, dated February 2, 1875; application led September 25, 1874.

same parts.

This invention consists in an improved mode or process of purifying and renewing the packing or absorbln g material without removing the same from the cylinder, all substantiallyr as I will now proceed to describe.

In the drawings, A is the cylinder in which the liquors are treated. B is the pump by which the liquors are forced into the cylinder. O is the supply-pipe through which the liquor is forced. D is the feed-pipe through which the liquor is drawn by the pump B. E is the waste-pipe through which the surplus liquor is allowed to escape into the receptacle from whence it was drawn. F represents a safetyvalve in the supply-pipe C, and Gr is a pressurea b c d ef represent the screens with which the cylinder is provided. g is a check-valve in the supply-pipe C.

In my improvements k is the separate airpump. m is the steam-pipe connecting the same with 4 the boiler, and is provided with a cock, w1. n is the pipe for conducting air or steam into the cylinder. I? is the superheater connected with the pipe n. 1" is a pipe connecting the steam-pipe m with the pipe n. s is the pressure-gage; t, safety-valve. c is the charging-screw in the cylinder. y is the double or T-shaped discharge-pipe at the bottom of the cylinder, each branch of which is provided with a cock, .r2 x3.

'Io enable those skilled in the art to fully understand and use my invention, I will proceed to describe its operation.

After the packing has been -used until it becomes foul, Iforce all of the liquor out ofthe cylinder, by means of a jet of steam introduced through the pipe m and the pipes r and n, rst closing the cocks mi and x4 and opening x5. I then remove the charging-screw o in the cylinder, and introduce certain chemicals in a liquid form-which may be sugar and starch-which unite with and take up the fusel-oil and other impurities left by the liquor in its passage through JEhe several different clarifying substances. 'lhese impurities are then, with the chemicals, expelled from the cylinder by ordinary steam pressure through the pipe y into a separate receptacle from that into which the rectified liquor is discharged, the cock x2 in the discharge-pi pe being rst closed and m3 opened for the purpose. By this means the fusel-oil and other impure substances extracted from the liquor are saved, and may be utilized for other purposes. I then open the cocks .nl and m4 and closest5 inthe piper, and introduce into the cylinder, through the pipes m and n, a jet of steam, which passes through the superheater l?, and is thereby raised to 3000 Farenheit, more or less, as is found necessary. This steam in its passage through the cylinder thoroughly carbonizes and renews the clarifying material without the necessity of its removal from the cylinder, and the apparatus is again ready to continue the rectifying operation, thus economizing much time and material.V

I have mentioned as chemicals, to be introduced at the charging screw o, sugar and starch, but any other substances which will readily combine with and carry off the fuseloil and other impurities, withoutl leaving any deleterious residuum or destroying the character of the packing, may be used. These chemicals are adapted to the purification of the packing, after spirits have been clarified. Other suitable substances may be used after the clarification of sirups or oils. The vsuperheater P may be heated with either charcoal or gas, and is only intended to be used during the cleaning process.

PATENT GEEIGE.

whereby the grosser and valuable deposits are removed, and by them introducing superheated steam into the top of the cylinder, and forcing it through the packing or absorbing material, whereby the finer impurities are removed, substantially as described, and for the purpose specified.
